Buy it, watch it, drool over it, and discuss it here! My girlfriend bought it for me today before I was out of my last class (she's the greatest!). Just the thought of 45 additional minutes makes me want to wet myself! Notes on the inside said that there are over 100 interviews with cast and crew members, just in case you want the opinions and expertise of just about everyone that had anything to do with it! What I imagine will be the best extra feature is the documentary on Gollum... which goes through every stage of creation. I'm sure that will be amazing! I'll post more once I've had time to go through more of it.
